I would like to teach EFL in a university/further education college. Would a course like this help? I have a CELTA and four years experience. I know I will have to add to my qualifications, but I am confused as to what I should do. Grateful for any advice or experiences.

It's always very hard for others to tell you what would suit you, beyond saying that the place [in this case a university] is a very reputable one, or else an unknown one. Ulter is very reputable, of course.

In my view, the trend in language teaching seems to be to use the internet more and more, and so a qualification in how to teach language online would be the most valuable asset anyone could get, beyond basic qualifications of course.
